ENGINE-VALVE.

To all whom t may concern:

Be it known that I, OLIVER A. REED, a citizen of the United States of America, and a resident of Plainfield, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Engine-Valves, of which the following is a specification.

The object of this invention is toprovide a valve constructed to serve ports of two power cylinders of an engine and to further organize the engine with two such valves in which one controls the inlet ports of the two power cylinders andthe other controls the exhaust ports of the two power cylinders.

A further object of the invention is to provide a valve wherein all the ports over which the valve operates are either all inlet ports, or all exhaust ports, so that there will be no inequalities of expansion tending to distort and unseat the valve.

In the accompanying three sheets of drawings which form a part of this application- Figure 1 is a plan showing the upper ends of two power cylinders ofan explosive engine, with associated valves embodying my invention, Fig. 2 is a section through one of the power cylinders on the line -II-II of Fig. 1 and elevation of the valve cylinders. Fig. 3 is a section through the valve cylinders and crank case on the line III-III of Fig. 2 and an elevation of the rearward power cylinder. Fig. ai' is a section to an enlarged scale through the exhaust valve cylinder, showing a construction for cooling the cup valve.

The engine shown is of the four-cycle type, with a forward power cylinder 1 and a rearward power cylinder 2, but the engine as a whole is not limited to two power cylinders, as others may be added to secure balance of reciprocating parts and further equalize the power. The power cylinders as shown are connected to the same crank and make their strokes at the same time, but this is not essential. They are preferably tired alternately.

The charge is admitted through an inlet valve cylinder 3 being delivered to this cylinder through a pipe 4. Surrounding the valve cylinder and communicating with the forward power cylinder is a port 5 and above this port is a second port 6 which communicantes with reaiwvardl power cylinder.

Vpiston cup valve 7 is mechanically opthe relie. Qrlaflelt fren. een@ Specification of Letters Patent.

through a` lever 9 which carries a cam roller l0 and connects with the valve through a rod 11. The downward movement of the valve is insured by a spring 12 when the form of cam is such as to render this necessary. The cup valve is provided with a port 13 which is brought into register with the port to the forward power cylinder when the valve is at the lower limit of its stroke and which is brought into register with the port to the rearward power cylinder when the valve is at the upper limit of its stroke, or vice versa. The valve in other positions closes these ports to the power cylinders and is provided with packing rings 14 14 which prevent leakage. The exhaust valve cylinder 15 is located on the opposite side of the pair of power cylinders from the inlet valve cylinder and is connected with the power cylinders byv ports 16 and 17 in the same way and is provided with a mechanically operated cup valve 18 of the same construction. This valve is operated from a camA 1,9 properly shaped to open the valves at the proper time. i

In the form shown in Fig. 4 an exhaust head 20 projects from the top of the exhaust valve cylinder with-in the cup valve andE has ports 21 21 which register with the port of the cup valve when the port of the valve is in register with either of the ports of; the valve cylinder. This exhaust head is waterjacketed, the water being circulated through an inlet 22v and an outlet 23. The exhaust head protects,- the interior of the valve fromL the heated gases and the cup valve slides betweeny cooled walls. The customary water-jacketing outside of the power cylinders and exhaust valvecylinder is not shown and will be readily understood and employed where air-cooling is insufficient.

I do not limit my invention to the operation of the valves by means of camsl as any suitable valve operating mechanism mayl be substituted therefor.

`What I claiml as new and desire to secure by Letters Patent of the United States is- 1. In an engine, the combination of two power cylinders, a mechanically operated reciprocating inlet Irvalve, an inlet port between the valve and each power cylinder, the valve being constructedl to open the inlet port of one power cylinder when in one position and, .to open the inlet port of the other rfi-Wer @vlinder when. in anptlierf substaatiallr as flesallied Regione,

2.

3. In an engine, the combination oi two power cylinders, a pipe, a TJalye cylinder, separate ports between the valve cylinder and each power cylinder, and a mechanically operated piston valve constructed to connect the port of one power cylinder with the pipe when in one position and to connect the port of kthe other power cylinder with the pipe when in another position, substantially as described.
